Abstract
Intercropping, an age old agricultural practice of cultivating two or more crops in the same space at the same time is generally adopted for more production by utilizing available growth resources. Choice of crops is very important to reap a better harvest from intercropping. The selection of a suitable intercropping system is sort of com...
The scope for enhancement of productivity under irrigated conditions is limited because of over-exploitation of available resources, but there is ample opportunity for boosting yield in drylands by adopting suitable crops and cropping systems. The agricultural sustainability in drylands is comparatively hard to achieve due to different constraints...
Intensive agriculture is based on the use of high energy inputs, quality planting materials with assured irrigation, but it failed to assure agricultural sustainability because of creation of ecological imbalance and degradation of natural resources. On the other hand, intercropping system, also known as mixed cropping or polyculture, a traditional...
Global climate change is impacting havoc on the growth and productivity of various plants. Among different abiotic stresses mainly caused by climate change, the thermo-stresses, that is, stresses caused by heat and cold, are of prime importance in influencing the physiological and metabolic activities of plants.
